摘要：
Photocatalytic degradation of organic pollutants represents a highly promising strategy for environmental remediation. Despite Bi4O5Br2 possesses a unique layered structure, its photocatalytic efficiency is hindered by the rapid recombination of photogenerated carriers. To overcome this limitation, a direct Z-scheme Bi4O5Br2/ CdS heterojunction is constructed, which not only enhances the carrier separation efficiency, but also maintains strong redox capabilities. The optimized 0.2Bi4O5Br2/CdS composite exhibits a RhB degradation efficiency approximately four and two times higher than pristine Bi4O5Br2 and CdS, respectively. This study offers valuable understanding for the design of advanced photocatalysts in environmental applications.
